方法300包括使用多个加工工艺和相关参数(馈送、速度、工具磨损和切割深度)执行310特性标本低循环疲劳(LCF)试验设计(DOE)。 The method 300 includes using a plurality of processing and related parameters (feed speed, tool wear and depth of cut) 310 performs low cycle fatigue properties of the specimen (the LCF) DOE (DOE). 在示范实施例中,DOE包括标本设计、标本几何形状的寿命校正以及材料i普系的寿命校正。 In the exemplary embodiment, the DOE design comprises a specimen, the specimen geometry correction life and the life of Pu-based correction material i.

在识别可影响零件的参数之后,确定为了保证安全工作这些参数中每个参数的可允许范围。 After identifying the parts of the influencing parameters, in order to ensure safe operation of these determined parameters, the allowable range for each parameter. 本文所用的安全工作是指其中达到可接受完整低循环疲劳结果的工作。 As used herein, security means which achieve an acceptable result of low cycle fatigue complete work. 例如,在三个参数识别为重要的情况下, 需要确定全部三个参数同时安全的可允许范围。 For example, in the three parameters identified as an important case, all three parameters determined at the same time secure the allowable range. 统计分析用于确保工艺在该范围内是安全的。 Statistical analysis is used to ensure that the process in this range is safe.

工艺测量统计用于分析工艺评估数据和评估结果。 Statistical analysis for process measurement data and evaluation result evaluation process. 使用工艺测量统计对每个工艺评定。 Technologies used to measure statistical assessment of each process. 工艺测量统计是工艺相对于低循环疲劳性能基线的可测量属性并且可表达为工艺测量指标。 Statistical process measurement process is measurable with respect to low cycle fatigue property and property may be expressed as a baseline measure of the process. 如果工艺评定结果大于预定指标数,则该工艺被认为是健壮的工艺。 If the evaluation result is greater than a predetermined number of process indicator, the process is considered to be a robust process. 如果工艺评定结果略低于预定指标数,则进一步评估该工艺以验证其是否是健壮的工艺,而如果工艺评定结果低于预定指标数,则该工艺被认为不是健壮的工艺在示范实施例中,使用试样执行312低循环疲劳试验。 If the process evaluation results slightly lower than a predetermined index number, the process is further evaluated to verify whether it is a robust process, and if the result is less than a predetermined number of process assessment indicators, the process is a process that is not robust in the exemplary embodiment , using the sample 312 perform a low cycle fatigue test. 对于每个工艺,在测试标本上执行工艺时,某些参数保持不变,而其它参数则会变化。 For each process, the process is performed on the test specimen, certain parameters remain unchanged, while the other parameters will vary. 统计分析用于验证标本设计准确表示制造期间受该工艺影响的每个零件。 Statistical analysis is used to verify an accurate representation of the sample design of each part by the impact of the process during manufacture. 此外,确定寿命校正以说明测试标本和实际零件的几何形状之间的差异。 In addition, the lifetime is determined to account for differences between a correction test specimens and the actual geometry of the part. 计算测试标本的材料谱系以说明用于制造每个标本和零件的材料样本之间的材料属性的可变性。 Test specimens pedigree material calculated to account for variability in material properties between the materials used to manufacture samples of each specimen and parts. 此外,在各种压力水平和温度下执行测试。 In addition, a test is performed at various pressure levels and temperatures. 选择压力水平和温度以适当应对燃气涡轮发动机的工作条件。 Selected pressure level and temperature to respond appropriately to operating conditions of the gas turbine engine. 可在有和没有零件制造典型后处理的情况下进行测试。 Can be tested with and without post-processing part for producing typical situation. 分析314结果测试数据以说明和校正工艺造成的寿命变动程度(life variation)改变和平均寿命偏差(mean life shift)。 Analysis of the results of 314 test data on the extent of changes in the life and correct process result (life variation) changes and the average life deviation (mean life shift). 平均寿命偏差是指示评估结果的平均值或平均与标准之间的相似性的度量。 The average life expectancy is a measure of the deviation of the similarity between the evaluation results indicating the average or mean and standard. 工艺造成的寿命变动程度是测量结果可变性相对于标准参考群体的可变性的度量。 Degree life is caused by changes in the process variable measurement phase measure of the variability of the standard reference population. 这两个度量用于表达加工的零件是好于还是差于标准及好差程度。 These two metrics used to express machined parts is better than or worse than standard and a good degree of difference. 例如,多个零件的评估结果可指示,在平均上,加工的标本零件仅略差于标准,但对零件的进一步分析可发现,虽然某些标本满足标准,测试结果当中可变性很大,因此其它零件远远达不到标准。 For example, parts of the plurality of evaluation results may indicate that, on average, only slightly worse parts machined in the standard sample, but further analysis of the components can be found, although some samples meet the criteria, which may be a large variability of the test results, so other parts far below the standard. 在许多情况下,具有任何达不到标准的结果表示工艺达不到标准,即使大部分零件处于标准容差之内。 In many cases, the result of not having any standard process represents not up to standard, even though most of the components are within the standard of tolerance. 结合使用平均寿命和寿命偏差可提供对工艺性能的准确评估。 Average life and life expectancy may provide an accurate assessment of variations in process performance binding. 方法300包括在每组工艺条件下建立316 LCF 寿命分布。 The method 300 includes establishing 316 LCF life distribution of each group under the process conditions.
